This class can serve images added to a MySQL database table.

It can execute SQL queries to store uploaded images files in a given MySQL table.

The class can also retrieve from the database table and serve image data for displaying as the current script output, retrieve the list of all images stored in the database, replace a given image already stored in the database table, and delete a given image from the database.

SQLimg

Facilitates the storage and delivery of small images via MySQL. This method is far faster than traditional methods, and potentially less error-prone when uploading images often.

$con: An optional database connection (optimization)
returns an associative array of keys and types

exists($key, $con=false) Determine weather or not a given image exists

$key: The image's unique key
$con: An optional database connection (optimization)
returns boolean

display($key) Display a stored image - CALL BEFORE HEADERS ARE SENT

$key: The image's unique key

upload($file, $key=null) Store an image through upload - uses the $_FILES superglobal

$file: The URL key to search for a file
$key: An image to replace (optional)
returns false if the image could not be uploaded, the new unique key otherwise

remove($key) Remove a stored image

$key: The image's unique key
returns false if the image did not exist, true otherwise

add($data, $type) Store a new image

$data: the image's binary
$type: the image's format
returns the image's unique key, or false on failure
